About me











Duke undergraduate research opportunities in math for summer 2024: Math+ and PRUV have both concluded for the summer. The Math+ 2024 web page has information about each of this year's 5 projects. (July 2024)

Solutions to the 2023 Putnam competition are now available. (December 2023)

I was an organizer for Frontiers in Geometry and Topology, the 2022 graduate summer school and research conference in honor of Tom Mrowka. Here are the relevant web pages for the graduate summer school and the research conference. (May 2022)

I help to organize the Triangle Topology Seminar, a joint seminar between Duke, NCSU, and UNC. Here is a link to upcoming seminars.

I am an editor for the journal Quantum Topology. Please send me a message if you are interested in submitting an article, especially in symplectic and contact topology.
